Jenkins bị treo ngẫu nhiên

Question

máy chủ jenkins của tôi bị lỗi ngẫu nhiên, vì vậy tôi đảm bảo có phiên bản mới nhất và kiểm tra nhật ký, nhưng chúng không cung cấp cho tôi thông tin hữu ích. Câu hỏi của tôi là: Làm thế nào để gỡ lỗi các tai nạn này? Có cách nào để tăng loglevel không?

Đây là của tôi log-đầu ra:

Bất kỳ gợi ý cho tôi?

Answer 1

Để tăng mức độ log của Jenkins bản thân, sử dụng các thông số sau khi bắt đầu Jenkins qua dòng lệnh:

-Djava.util.logging.loglevel=FINE 

này nên thay đổi đăng nhập như được hiển thị trong giao diện Jenkins.
